DRAW-BAR CARRIER.

Specification of Letters Patent.

Patented Feb. 16,1909.

Application filed September 9, 1907. Serial No. $92,007:

To all i 'honi it may concern;

Be it known that I, Anrnnn D. Molvnoiv ran. a cit U1 of the cnited States, residing at. Memphis. in the county of Shelby and State of cnnesscc, have invented certain new and useful Improvements in Draw-Bar Carriers; and i do hereby declare the following; to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it apperf om i'vearingon one side when the trailer drau liead would run against the front car in training curves, and to allow of vertical.

travel above or below the normal or center 1 'lineto compensate for uneven tracks.

l\ 1th these ob ects infview, my invention .30 consists in the constructions and combinations of'parts as hereinafter described and claimed.

T 1' 'ra' in .e- .ncompanymg innin s. ii urc l-is a top view of a portion of a car platnor is that the draw bar heads mstead of .orm showing my invention as applied Fig. 2 is a cross section on an enarged scale, on the line 2-2 of Fig. 1, lookin the direction of the arrows, and a part being broken away to show the interior 44 construction. Fig. 3 is a cross section on he line 3- 3 of Fig. 2, looking in the direction of the arrows. Fig. -l is a cross section on the line sl l of Fig. '2, looking in the direction of the arrows. Fig. is a front view 45 of one of he retainingcastings, and Fig. 6

"is a end 'iew thereof.

n represents a car' platform. I) a cross beam, and c a draw bar pivotally attached thereto, all of th-sc parts being of the usual on or any suitable construction. Underneath the front of the platforn'i, beams (Z are pro vided to which is bolted a curved I-beam c, which serves as'a guide for the draw bar.

' Engaging the lower flange of the i-beam c s: are two similarly shaped and oppositelydisposed castings f and 9, having at the top projections h which engage the lowei part of the I-heani, and having at the bottom projections i which fit against each other, making the two castings togetler a box, the

two parts: of the box being firmly .united by bolts The QIOJOCtlDg parts 2' .irrbeveled. as shown in Fig. 4-, so thatthey will fit firmly against each other. These projections are provided with seats is for the spiral springs m, each of said'projections z' forming appnoximately one-half of one of said seats. On the springs m rests the retaining yoke throughwhich the draw bar passes. This yoke provided with ahorizontal portion 12-, uprightportions 0, and

horizontal portions 1 which latter rest upon the springs m. An additional yoke q is provided, made substantially in the shape hi the yoke 02, but terminating in eyes '1', through which the bolts 7' pass. This yoke 1 made stronger than'the yoke 11, and is intended to be an additional safeguard in case the yoke n is pressed suddenlyand violently down upon the springs m, which might occur in case of a derailment.

By the construction described the objects of my invention are fully attained. Furthermore, when the draw bar is not in use, the springs push the yoke n up against the I- beam 6 with suliicient pressure to keep the draw bar from swinging onthe I-bea'm as the car lurchcs.

Another advantage in the use of this carbecoining worn on their top faces are held up in such a manner that the wear is distrib uted over the entire surface. The wide range of vertical travel ofthe draw bar is also an advantage, and especially so when the tracks are uneven. Furthermore, the carrier always holds the draw bar level, and this adds considerably to the appearance of the car. It should be noticed also that the castings f and g are recessed in the center, but that the strain due to the compression of the springs m always comes near the ends of said castings where they are strongest.

Having thus described my invention, I claim 1. The combination of a car platform, a draw bar pivotally secured thereto, supporting means for said draw bar, and a curved uide for said sup orting means secured to said platform, sai supporting means being draw bar engag ng said porting means for said provided with springs no rmally holding said on said guide, substanporting means being'provided with a yoke through which said draw bar passes, and

springs holding said yoke in contact with sald I-beam, substant ally as described.

3. TllB QOFflblnfltlOIl of a car platform, a

draw bar pivotally secured thereto, a curved platform, and sup-.

guide fastened to said draw bar movablysupported on said guide, said means including similarly shaped castings embracing a part of said guide, a yoke through which said draw bar passes, and

against said guide, substantially as described. y 7

4. Tl1ecombination of acar platform, a draw 1:21 pivot'ally secured thereto, a curved guide'fastene'd to said platform, and supporting mean's for said draw, bar movabiy held by said guide,

I-beam, said sup springs seated in said castings normally holdlng said yoke said means including castings, and a yoke having bent upper with which said springs engage, substansubstantially as described.

castings embracing a part of said guide, a yoke through which said draw bar passes, springs seated in said castings and bearing against the ends of said yoke,'and a supplemental yoke secured to said cast1ngs,-substantially as described. v

'5. The combination of a draw bar and supporting means therefor, said means including two similarly shaped but oppositelydisposed castings. springs'supported in saiid en s tially as described.

6. The combination of a draw bar-and supporting means therefor, said means including two similarly shaped but oppositelydisposed castings, bolts uniting said castings, a yoke through which said draw bar passes, springs seated in said castings and bearing against said yoke, and a second safety yoke,

In testiinony whereof, l affix my signature, in presence of two witnesses.
